Application filed February 6, 1925. Serial No. 7,319.

This invention relates to machines for removing train hose couplings, nipples and clamps from old hose, and assembling them with new hose, and comprises all improvements disclosed in this application. The primary object is to produce a rugged machine composed of a minimum number of parts which is so constructed that the operatorcan produce a maximum output of work with a minimum expenditure of etfort and, time, thereby enabling him to maintain a relatively high rate of output over an extended period of time. In the main, this object is attained by having all the gripping, dismantling and assembling devices operate in a horizontal direction to provide for the easy placing and removal of train hose parts by the operator and at the same time to permit his easy constant watching of all operations. Also by operating all these devices by easily controlled, quick .acting, power means, with the controls so centrally and conveniently placed as to be readily operable by the hands and feet of the operator with a minimum expenditure of his time and strength. To further aid in increased output, the dismantlingand assembling tools are so improved as to operate without the use of latches to hold the couplings and nipples in position, and a number of tools are arranged on each of two turrets so as to be quickly indexable to operative position.

The above and other objects which will hereinafter appear, are attained by new and useful improvements as disclosed 111 this application. To enable others skilled in the art to fully understand the essential features of the improvements, drawings have been annexed as a part of this disclosure.

The machine comprises a main frame 1 supported on legs 2 and having a bed 3 provided with openings 4i, 5, leading respectively to chutes 6, 7. i Vays 8, 9, extend longitudinally of the bed and communicate respectively with openings 4, 5. Sliding in ways 8, 9, are turret slides 10, 11, on which are rotatably mounted, turret blocks 12, 13. Both turret constructions are similar, differing only in minor details. Therefore only one turret will be specifically shown and described. Turret slide 11 (Fig. 11) has an upstanding pivot portion 14, pivotally carrying the turret block 18. Cover plate'15 is secured to portion let by bolts 16 engaging in holes The cover plate has a hole 18 capable of registering with any one of the four holes 19 in the turret block. Thus by swinging the turret block around until any desired hole 19 registers with hole 18 and then inserting index pin therein, the turret block may be readily indexed to bring any desired tool mounted thereon, into operative position. In its preferred form, the

Fig.

turret block has a dismantling or pulling tool 167 comprising preferably integrally formed arms 21, 22, connected by tie plates 23, 24, preferably by welding. Secured to the tie plates are guide members :25, 26. Slidably mounted on guides 25, 26 are pairs of puller plates 27, 28, secured in desired adjusted position preferably by bolts. Plates 27, 28 being secured by bolts 29, passing through holes in plates 27, 28 and slots 30 in tie plates 23, 24. it will thus be seen that slots 30 permit plates 27, 28, to be moved away from or toward each other to provide upwardly open puller slots 31, 82, of adjustable width. Plates 2?, 28, extend above the puller blocks to make it a little easier for the operator to get the hose in position to be stripped, and to prevent the hose from popping out of the fixture, and also to make it unnecessary to place the hose so accurately in the slots of the pulling heads. The turret block also has pairs of ears 83 to which the desired tools are connected by coupling pins 3% (Fig. 1). While four tools are shown on each turret herein disclosed, it is obvious that the turrets can be constructed to accommodate more or less tools if so desired.

Turret slide 11 has a central vertical slot in which is mounted the upper end of lever 36 and having a pin and slot connection with slide 11 by meansofpin 37, and slot 38 in lever 36, which is pivoted to the main frame at 39. Similarly the turret slide 10 is connected to lever 40 pivoted at 41. Levers 36 and 40 are connected together by link 42 pivoted at 43 and 44. Thus, when the lower end of lever 36 is operated to the right, both turrets will move toward each other, and when the lever 36 is operated to the left the turrets will move away from each other.

Connected to the under part of the ma chine, are two air cylinders e5, e6. These cylinders are secured together mechanically, but have an intervening plate at? which acts as a common head for both cylinders. Thus the cylinders are entirely independent of each other in operation. These cylinders preferably have integral extensions 48, 4:9 bolted to the main frame. An integral foot on cylinder 4:5 aids in supporting the center portion of the machine. Piston 51 in cylinder 45 is connected to piston rod 52 which has a elevis 53 connected to lever 36 by a pin and slot connection as shown. The far end of the piston rod extends through a bumper spring 54 mounted in bumper box 55, and has washer 56 held in place by collar 57 by means of pins 58 or otherwise. Bumper box cover 59 has an integrally extending guard 60. The operation of piston 51, lever 36, and the turrets connected thereto, is effected by means of air valve 61, operated by handle 62. A main air supply pipe 68, supplies compressed air or other desired fluid medium to the top of valve 61 at 68. Pipes 64, lead from the valve 61 to opposite ends of cylinder 45. 66 is the exhaust pipe leading to main exhaust pipe 67. hen lever 62 is moved to the right as shown in Fig. 2, air is admitted through pipe 65 to the right end of cylinder d5, and pipes 64: and 66 are connected through valve 61 to ex haust air from the left end of cylinder l5. Thus piston 51 moves to the left and through the connections described, causes the turrets to move away from each other. Moving lever 62 to the left, admits air to the left end of cylinder 45, connects pipes 65 and 66 through valve 61 to exhaust air from the rightend of cylinder 45, and thus causes the turrets to move toward each other.

iii: the left end of the machine is a shear comprising lined and movable knives 69, 70. The knife ?0 is mounted on a lever 71 pivoted to the frame at T2. The top of lever 71 is below the path of movement of the turret block 12 so as not to interfere with the indexing or reciprocation of the turret. The lower end of lever '71 has pin and slot connection to a clevis 73 on the end of piston rod 74lconnected to piston 75 in cylinder 46. To operate the shear, air from main supply pipe 63 enters the top of valve 76 at 77. Pipes l8, 79 lead from valve 76 to opposite ends of cylinder 46. 80 is the exhaust pipe leading to main exhaust pipe 67. Elbow lever 81 is normally pulled to the rightby coil spring 82 connected to pipe (53 by collar Thus lever 81 normally held by spring 82 from pipe 77 through pipe 75) to the right end of cylinder 46, while air is exhausted from the left end of cylinder -16 through pipes 78 and 80. Thus piston '75 normally is at the left of cylinder 16 and knives 69, 70 of the shear are normally open. irn elastic buffer block 84 cushions lever 71, when the latter is moved to open the shear. To close the shear knives, a link 85 connects lever Sl to foot operated treadle or lever 86. which latter is pivoted at 87 to bracket 90 connected to the machine frame. Thus when the operator steps on treadle 86, valve 76 is operated to supply air through pipes 77 and 75% to the left end of cylinder 46, and to exhaust air from the rightend of cylinder 46 through pipes 79 and 80. Thus piston 75 moves to the right in cylinder 4-6 to close knife 70.

By referring to Figs. 2 and itwill be seen that link 42 is located beneath the bottom plate 91 of chute 6 and does not interfere therewith in operation. Bottom plate 91 is secured in position. by bolts 92, with the other end of the bottom plate resting on the edge 93 of chute 6. Bottom plate 9 of chute 7 similarly held in place. Slot 95 (Fig. l) in the bed and sloping part of the frame 98 (Fig. 2) is to accomn'iodate lever 40 while moving back and forth in operating in such position that air passes ill) turret slide 10. A shield preferably comprising a piece of leather 96 is fastened at 97 to turret slide 10 and extends outwardly over slot 95. The leather is wide enough to effectively prevent couplings from entering the slot. Y

From Figs. 2 and 6'it will be seen that lever 42 passes directly through a slot 99 in the side walls of chute 7 above bottom plate 94. This slot 99 extends. on through the sloping portion 100 of .the frame and into the bed. Thus ample provision is afforded for link 42 and lever 36 in their movement back and forth in the operation of the turret head 11. A piece of leather 101 similar to leather 96, is attached at 102 to turret slide 11 and extends forward over slot 99 to pre vent nipples from entering the slot. To prevent nipples falling between link. 42 and rear wall 103 of chute 7, an angle iron guard 104-. is fastened at 105. Owing to link 42 being higher at the right end of the 1nachine than at the left end, it is found desirable to locate the chute 7 nearer the center of the machine and lower down, than in the case of chute 6, so that link 42 will clear bottom plate 94, and so the wide right end of link 42 where it connects with lever 36, will clear chute 7.

Extending transversely across the bed 3 of the frame are three slideways or ways 106, 107, 108. Referring to Figs. 1 and 7, a pair of slides 109, 110, travel in ways 108. Sl des 109, 110 have upstanding squared portions 121, 1.22, over whichare placed clamp closing heads or blocks 123, 124. Secured to the rear of the frame is a cylinder 111, contamtwo opposed pistons 112, 113. Piston 113 is connected by hollow piston rod 114 to slide 109. Piston 112 is connected by solid piston rod 115'to slide 110. Thus piston 115 extends through hollow piston rod 114 so that each is free to move independently of the other. At the center of 'slideway 108 is secured a stop 116, and at the ends of the slide way are stops 117, 118. All these stops are preferably fastened by pins 198. At the front of the machine (side opposite the air cylinder 111) a stop plate 119. is secured over the end of slideway 108. Thus when air is admitted through pipe 120, pistons 112, 113, move away from each other causing slides 109, 110 to move toward each other until blocks 123, 1.24, engage an intended article or until the slides engage center stop 116. Sometimes, due to unequal friction of the parts, one piston. moves faster than the'other. In this case, the faster moving piston will travel until its slide strikes center stop 116,

when the other piston will continue to move until its slide also engages stop 116 or until the block on its slide engages an intended article. When air is admitted through pipes 125, the pistons move toward each other and the slides move away from each other until the slides strike stops 117 and 118. As slide way 106 with its slides 126, 127, clamp closing blocks 128, 129, cylinder 130 and other parts are identical with the parts operating slides 109, 110, they will notbefurther described. It is to be noted, however that as jaws 182, 183,191, 192 are at one side of blocks 123, 124, and as blocks 128,129, are similarly constructed, except that blocks 123,

124 are rights and 128, 129, are lefts, an

adjustable effect can be secured by suitably interchanging the blocks. Thus by interchanging (Fig. 1') block 124 with block 129 and block 123 with block 128, jaws 191, 192 will suit shorter hose. Excepting in minor details, the parts operating in slideway 107, are very similar to those in slideways 106,108. The outer stops 131, 132, are secured nearer the center of the machine than stops 117, 118, and therefore the amplitude of travel of the slides is less. Thus a much shorter air cylinder 133 is sufficient. Instead of a center stop placed in the slideway 107, a hose trough 134 spans the slideway and is secured to the bed. The hose trough 134 acts as a center stop for the slides in'guideway 107 and also as a hose support as will be later described. The slides have upstanding rectangular portions 135, 136, over which are placed hose clamping blocks or heads, 137, 138.

Operation of blocks 123, 124, by cylinder 111, is controlled by valve 139 (Fig. 3) operated by lever 140. This lever 140 is pivotednear the middle, the same as lever 141 wh1ch operates cylinder 1.30. Connected to one end of lever 140 is a spring 142 which is a secured to pipe to normally hold the valve in such position that air is admitted from main air supply pipe 63 to air supply pipe which has two branches which enter the opposite ends of cylinder 111 (Fig. 7) to cause the pistons to move toward each other-and thus to cause the blocks 123,124. to move away from each other to open posi tion as shown in Fig. 1. At the same time air en hausts through pipe 120 to main exhaust pipe 67. To the oppositeend of lever is secured .a link 143 connected to foot treadle lever 144' pivoted at 145to cylinder 45 (Fig. 2) and providing a foot engaging portion or pedal 146 at the front of the machine. When part 146 is pressed down by the foot of the operator, link 143 pushes lever 140 against action of spring 142 to admit air from supply pipe 63 throughpipe 120 to the center of cylinder 111 to cause pistons to move away from each other, and hence to cause blocks 123, 124, to move toward each other. At the same time air exhausts through pipe 125 to main exhaust pipe 67. The valve and other mechanism for operating cylinder 130 is identical with thatfor operating cylinder 111fand will not be described in detail, being operated by foot treadle lever 147 pivoted at 148 and providing a foot engaging portion or pedal 149 at the front of the machine.

Operation of blocks 137, 138 by cylinder 133 is controlled by valve 150 (Fig. 3) op erated by lever 151 (Fig. 2) through rod 152 extending through the machine from the front to the rear (Fig. 4.) and being connected to the'valve 150 through levers 153, 154 and link 155. When lever 151 is thrown to the left of the operator (Fig. 2) air is admitted from main air supply pipe 63 into the. top of valve 150 and thence through pipe 156 and its branches to the opposite ends of cylinder 133, causing the pistons therein to move toward each other and heads 137, 138 to move away from each other to open position. At the same time air exhausts from the center of cylinder 133 through pipe 157 into main exhaust pipe 67. lVhen lever 151 is thrown to the right of the operator, air is admitted from pipe 63 through pipe 157 to the center of cylinder 133, causing the pistons to move away from each other and the blocks 137, 138 to move toward each other. At the same time air exhausts from the ends of cylinder 133 through pipe 156 into main exhaust pipe 67. Thus the action of cylinder 133 is similar to that of cylinders 111, and 130, except that control valve 150 is lever operated in both directions without any spring. It will thus be noted for ease of understanding that air enters all the air control valves at the top from main air supply pipe 63 and exhausts from the bottom of all the valves into main exhaust pipe 67.

In operating this machine to dismantle and assemble train hose, three different sizes of hose are commonly met with, namely 2 steam, air, and signal hose. In the dismantling operation, all three sizes of hose are handled by the same hose trough and gripping jaws. Thus the hose would be laid in the concave portion 158 of hose trough 134 (Figs. 1 and 8') and the blocks 137 138, placed on upstanding portions 135, 136, respectively with the serrated jaws 159, 160, facing each other, as in Fig. 1. In the assembling operation, different shape jaws are used and these jaws are preferably of three sizes, one pair preferably for each corresponding size of hose. But the same hose trough 134 serves for all dismantling and assembling operations. Thus when air hose is to be assembled, blocks 137, 138 are placed respectively on portions 136, 135 so that the concave jaws 161, 162 (Fig. 8) face each other to provide a smooth cylindrical gripping surface of suitable size to grip a hose. The lower portionsof jaws 161, 162 are cut away to accommodate hose trough 13 1, which is preferably secured to the bed of the machine by screws taking through holes 163 in the trough. Jaws 161, 162 preferably are of a size to properly center new air hose without any substantial clamping effect, so that no injury can be done to the hose.

To clamp steam hose, a pair of blocks 163, 16%, having gripping jaws 165, 166 are slipped over portions 135, 136, in place of heads 137, 138. To clamp signal hose, smaller jaws similar to 163, 164 are used.

The right and left ends of the machine, are the ends at the right and left of the operator when he is at the front and facing the side of the machine where levers 62 and 151 are located. When dismantling or assembling hose, the nipples are always handled by the tools on the turret at. the right (nipple) end of the machine, and the couplings are always handled by the tools on the turret at the left (coupling) end of the machine.

Nipple dismantling tool 167 is similar to, but shorter than, coupling dismantling tool 168. Air hose nipple assembling tool 169, steam hose nipple assembling tool 170, and signal hose nipple assembling tool 171 are similar tools of different sizes used for assembling the nipples mentioned. They may be similar to the tool shown in Fig. 12 of Patent 1,461,578. Dismantling tool 168 is for pulling off air and signal hose couplings, while dismantling tool 172 is used for pulling steam hose couplings. Tool 173 is for assembling air and signal hose couplings on air and signal hose respectively. T001 1741 is for assembling steam hose couplings on steam hose.

Dismantling operation for air 07* signal 7z.0se.The operator first shears the clamp bolts on the clamps which hold the couplings and nipples in the hose by pressing down treadle 86 which operates shear knife 7 0. 1Vith dismantling tools 167, 168, in line with the travel of the turrets, as shown in Fig. 1, lever 62 is moved to the left to bring tools 167, 168 toward each other to proper position. A hose is. then placed on trough 134: with the hose clamp to the left of plates 28, while neck 175 (Fig. 19) is placed in slot 31 with enlarged portion 176 of coupling to the left of plates 27. At the right end of the machine, the hose is placed in slot 32 with the hose clamp to the right of plates 28, and the enlarged part of the nipple to the right of plates 27. Lever 151 is now moved to the right, causing serrated jaws 159, 160, to firmly grip the hose. Lever 62 is then moved to the right, causing the dismantling tools 167, 168 to travel away from each other. Plates 28, 27 of tool 167 pull off the hose clamp and nipple respectively, which fall down between arms 21, 22 of tool 167, strike leather strip 101 which cushions their fall and also prevents them falling into the slot 99. They then pass down through opening 5 011 to bottom 94 of chute 7 and out the rear side of the machine into any desired receptacle or truck. Similarly the hose clamp and coupling are pulled off by tool 168 at the left end ofthe machine and pass out through chute 6. Lever 151' preferably is of an integral box like con-- struction (Figs. 14 to 16) having a slot 184 in end wall 176 and upstandingstrengthening flanges 177. Runningaround the base is a strengthening flange 17 8. When a steam hose coupling is being pulled, its groove 179 (Fig. 18) rests in slot 184 with arm 180 resting on top of wall 181. In this instance the steam hosecoupling does not automatically fall into chute 6, but has to be lifted out by the operator.

Dismantling short Zarolccn hose.0n the nipple end of the machine, tools 169, 170, 171, are replaced by tools similar to that shown in Fig. 9 of Patent 1,461,578, one for each size of nipple to be pulled. Blocks 123, 124 are interchanged on portions 122, 121, so as to bring jaws 182, 183 into position facing each other. If the broken hose is long enough, it may be gripped by jaws 159, 160/ But when the hose'is short, jaws 182, 183 must be used. By means of pin 20 and holes 19, the turret may be indexed to bring the desired tool into operative position, tool 167 therefore swinging out of position. The operator steps on treadle 146, thereby causing jaws 182, 183, to grip the hose between the hose clamp and enlarged portion of the nipple. The nipple turret is brought forward, and the tool, such for example as that shown in Fig. 9 of Patent 1,461,578, and of suitable size for the kind of nipple to be pulled, is engaged in the nipple. The turret is then made to travel to the right, pulling the nipple out of the hose. The operator then lifts his foot oft treadle 146, whence spring 142 operates the air valve 139 to open the jaws 182, 183. For dismantling short hose having air or signal. couplings attached, neck 175 of the, coupling is engagedin slot 32 of tool 168 and by stepping 011 treadle 149jaws on heads 128, 129 similar to jaws 182, 183 are made to grip the hose. Plates 28 and slot 32 of tool 167 can be used similarly to pull nipples if desired. By using tools 172 with different sizes of slots, 184 to suit different size nipplesand couplings, tools 172 can also be used to pull nipples and conplings from short ends.

Assembling air and signal /i0sc.Heads 137, '138are placed respectivel over portions 136, 135 whereby jaws 161, 162 (Fig. 8) face each other. A piece of new hose with a loose hose clamp on each end, is laid on concave centering portion 158 of trough 134. Lever 151 is operated. to bring jaws 161, 162 into position to hold the hose properly centcred. Tools 173, 169 having been properly incexed to operative position, an air hose nipple is placed over tool 169, and an air hose coupling is placed on tool 17 3 with the gasket 185 in the face of the coupling (Fig. 19) resting onsurface 186 of tool 173, and tongue 187 of tool 173 extending into throat or groove 188 of the coupling. The tongue 187 supports the coupling beyond its center of gravity so the coupling does not fall off.

Tillie operator new places his left hand on top 189 of the coupling andv moves lever 62 with his right hand to bring the turrets toward the hose. The nipple will be properly centered and pushed into the end of the hose without special attention, but the operator may require shifting the weight of his hand to center the stem 190 of the coupling to cause it to enter the hose. Lever 62 is now moved to the right to cause tools 173, 169 to recede from the coupling and nipple which remain in the hose. Lever 151 is then moved to open jaws 161, 162, leaving the hose lying in trough 134 with coupling and nipple in the hose with the hose clamps loose on the hose and ready to be tightened. The heads 123, 124, 128, 129, being in the position shown in 1 and 7, with clamp closing jaws 191,192, facing each other, the operator steps on treadle 146, which causes jaws191, 192 to firmly close the hose clamps on the hose, and while thusheld, the operator inserts and tightens the bolt and nut. The

operator releases treadle 14.6 which results in jaws 191, 192, receding. The operator then stops on treadlc 149 to similarly apply a bolt and nut'to the hose clamp at the coupling end of the hose, releasi-ngtreadle 149 as soon as the bolt and nut are secured in final position. The completely assembled hose is then lifted. off trough 134. Signal hose couplings are assembled by using the same tool 173 since signal hose couplings are very similar to the air hose coupling shown in Fig. 19. Signal hose nipples merely require a tool 171 similar to but smaller than tool 169.

Assembling steam 7L0sc.The operations are similar to those for assembling air and signal hose, except that a larger nipple tool 170 is used, and a special coupling assembling tool 174 is used. The steam hose coupling is placed on tool 174 with locking lug 193 (Fig. 18) resting on horizontal surface 194 of tool 174 (Figil), locking lug 195 resting on ledge 196, and with the operators hand resting on arm 180to hold the coupling on tool 174 and permit of the operator wabbling the coupling sutliciently to bring stem 19'? in line with the hose. The other operations are the same as for the air and signal hose.
